SEO and website upgrade. (selling one book.)

I need a website to sell my book and pdf book "How to Complete a PhD". I have a poorly made site that receives next to no traffic. i want HIGH google ranking. the e-book is to be automatically emailed or downloaded once the customer has paid for it via paypal. I can write/record content for the webpage and blog. i also want a new website url that will get me the most traffic (your choice). i can create a logo/take pictures or you can. **The KEY ****thing is obtaining traffic to the site!!!!!** so you need to explain how you will do this and provide previous examples. the key tabs will be: -Home ( what the book is about ect) -order now -about author -contact -other services -blog Thanks.
